WiFi extremely slow. Atheros AR9285 on Ubuntu 12.10
mi wireless conection is extremely slow. I have a 20 Mb/s conection, and torrents are downloading max at 150 KB/s.
I had this problem before, and was solved by entering "echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf" at the terminal. A few days ago, it came back.
I tried changing the kernel, currently i am trying with 3.5.0-17-generic i686, and have tried with 0-18, 0-19 and 3.6.9-030609.201
Notice the high amount of "Invalid misc:" in iwconfig (dont know what that means, but doesn't look good)
If you can help me, or help me reporting the problem so other can be benefited i will be thankful.
